Application filed October 29. 188 (No model.) l v To all whom it mayconccm': I

Be it known that I, CHARLES B. SMITH, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Mechanism for Rollingllingecllings, 850.; and do herehyeie clnre the following" to be it full, clear, and exact description of the invention, such as Will ennbio others skilled in the art to which it opportains to make and use the some, reference being; had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a port of this specification.

My invention relates to on improved method oi engraving or chasing fingenrings, napkim rings, and other analogous articles, and. also My invention consists of n metallic spool or sleeve, loosely fitted upon a stationary other, which serves to support the ring, 860., durin g the rolling; and finishing process. By making this spool in two parts, rings of {my practicable width and diameter may be rolled.

In the nccompsnyingdrewings, in which similorlettersofreferenceindicetelike po-rtsfllignre 1 represents a. perspective view of n olid spool or sleeve. Fig. 2 is n transverse sectional view of the spool, together with the arbor upon which it revolves, and also the engraved roll. Fig. 3 is a vertical longitudinal sectional view of the spool when made in two parts. Fig. 4 is a. vertical transverse section, on line o w of it revolves, showing the position of the spool end. roll when in the not of engraving or can bossing the ring. Fig. 5 is on end elevation, showing the lllitllllfll oi. supporting the endv of the spool-arbor. Fig. (i is stop view of Fig. 5, and also showing a port-ion of the holder in \vh ichthc spoolerloor is cdjustohly secured. Fig. 7 represents c modification oi'l ig. 5,whereby the arbor and spool are ndjnsted vertically against the engraved roll. 8 represents my invention as sed for finishing or hnrnish ing rings by employing a plain roll.

a, Fig. 1, is the spool, made of hardened steel or other suitable material, lmvine; flanges it formed thereon at each end, one flanges servihig to lntcrelly guide the ringnvhen the letter it brought in contact with the figured or pie-in adjustable in the directionroll 0. By dispensing with one flange of this spool and providing instead a sleeve, a which also loosely fits the spool-arbor c and is recessetito receive the spool a, a. spool is produced which can be adjusted to iit rings of diiiercnt Widths. Also, when this sleeve or flange a? is removed a ring of smaller (Home ter may be placed upon the spool than could be it both flanges were solid, pnrticnlnrly as it is desirable that the flanges should he'oi' considerable depth, in order that thering may he better and more properly guided. The spool at a instead of being straight may he made in c concave form or other desirable shape. The i 5* nrhor c" has formed thereon, and about midway of its'length, a. collar, o This arbor is oi-its-leegth, end is secured to the holder B by the set-screw a, and rests when in Working ports A.

B represents at movable holder, in which the arbor c is mounted, and ndjnstohly secured thereto by theset-screw s. Saidholdcris connterbored to receive"thc collar c of the nrhor. A reprcsentsa carriage upon which theholcler B may he pivoted, which also in turn may be mounted similarly to on ordinary lnthe-cerrioge, and by means of a. screw mode'to en gage with the roll 0, which revolves in station-- ary hearings; or, as in Fig. 7, tho carriage A may be given a. vertical reciprocating motion by means of s cam or other shite-hie mechanism.

The operation of transferring it design from the figured roll to the ring is no follows: The holder B is raised Whenthe cntewey portion oi the roll, (1 is opposite the arbor of, when the ring is placed noon and between the flanges oi" the spool. The holder is then dropped into position. and one revolution of the roll pro" dunes the design upon the sing. In erection it is fennel ncccssnry to locate, the spoolerhor o. little below the cooler oi. the figured roll, es shown, in Fig. 2.
